Until the 1920s Cetti’s Warblers bred only in a range extending from North Africa, Iberia and the Mediterranean countries, through Asia Minor, east to Afghanistan. They then began a northward expansion through western France. They reached the English Channel coast in 1961, making their first British appearance in Hampshire in March that year. British breeding was first confirmed in Kent in 1972 and by 2000 they had spread to most counties south of a line from the Wash to southern Wales. Bird Atlas 2007-2011 recorded them beginning to appear in North Wales and the Midlands.
In Wiltshire the first record occurred at Coate Water in October 1980 and the second at the same location a year later. There were further records in 1985 at Steeple Langford and Britford, and breeding was first confirmed in 1987 at Petersfinger. The 1988-91 Breeding Atlas recorded breeding in one 10km Wiltshire square and presence in three more. From then on they were regular on the Salisbury Avon and along the River Kennett, at the Cotswold Water Park and at Corsham Lake. Birds of Wiltshire recorded them in 13 tetrads with breeding in seven. Twenty years later, WTA2 recorded them in 45 locations with breeding confirmed or probable in 23 of them and the expansion has continued: the 2017 Wiltshire Bird Report (Hobby 44) recorded them at 75 sites in the county.
